Updates the display.<br><br>
Normally, the ViewPortControl display will automatically update if the viewport of the associated <a href="ChartViewer.htm">ChartViewer</a> object is changed. So calling <b>updateDisplay</b> is not necessary. However, if the display needs to be updated for other reasons, such as if the viewport border color has been modified, this method can be used to notify the ViewPortControl that the modification has been completed so that it can update the display.
